21、ASUREMENT PROCEDURES Part 2-23: Tests Sealing for non-pressurized closures of fibre optic devices FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object
22、of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications
23、(PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising
24、with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as
25、 nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
26、 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Commi
27、ttees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provi
28、de any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the late
29、st edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whet
30、her direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is in
31、dispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 613
32、00-2-23 has been prepared by subcommittee SC86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 1995. It constitutes a technical revision. Changes from the previous editi
33、on of the document are to reconsider the procedure and severity. 4 61300-2-23 IEC:2010 The text of this standard is based on the following documents: FDIS Report on voting 86B/3088/FDIS 86B/3102/RVD Full information on the voting for the approval of this standard can be found in the report on voting
34、 indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 61300 series, published under the general title, Fibre optic interconnecting and passive components Basic test and measurement procedures, can be found on th
35、e IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, rep
36、laced by a revised edition, or amended. 61300-2-23 IEC:2010 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-23: Tests Sealing for non-pressurized closures of fibre optic devices 1 Scope This part of IEC 61300 evaluates the effectiveness of th
37、e sealing of non-pressurized closures when subjecting to immersion in water. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the refer
38、enced document (including any amendments) applies.

40、7, test Qf: immersion. The specimen is submitted to a specified pressure by immersion in a water tank at a specified depth or in a high-pressure water chamber. After conditioning, the specimen is examined for penetrated water and checked for possible changes of characteristics. 3.2 Pre-conditioning
41、Specimens shall be configured according to the relevant specification and prepared for attenuation measurements according to IEC 61300-3-3. Pre-conditioning of the specimen shall be 2 h under normal atmospheric conditions described in IEC 61300-1. 3.3 Initial measurements The closures shall be visua
42、lly inspected and optically measured as well as mechanically checked. All closure sealing features shall be checked to as certain that they have been mounted correctly. 6 61300-2-23 IEC:2010 3.4 Conditioning The specimens shall be placed in the position as prescribed in the relevent specification an
43、d shall be completely immersed either in a water tank at a specified depth or in a pressure water chamber. The specimens shall be subjected to 5 m of the head of water or 48,9 kPa as required. When a tank is used, the specified head of water shall be measured above the highest point of the specimen.
44、 When a pressure water chamber is used, the water pressure shall be adjusted to 48,9 kPa. The specimen shall be conditioned for 7 days. During the conditioning the difference between the water and the specimen shall not be greater than 5 C. The temperatures of the specimen and of the water shall be
45、between 15 C and 35 C. 3.5 Recovery The closures shall be dried at standard atmospheric conditions for 24 h unless otherwise specified. 3.6 Final measurements The closures shall be examined for water penetration and shall be visually inspected and optically measured as well as mechanically checked a
46、s required by the relevant specification. 4 Apparatus The apparatus consists of either a water tank or a pressure water chamber in accordance with IEC 60068-2-17, test Qf. When a tank is used, the specified head of water shall be measured above the highest point of the specimen. When a high-pressure
47、 water chamber is used, the water pressure shall be adjusted to the pressure difference in Table 1. 5 Severity The severity consists of the height of water and test duration (See Tables 1 and 2).
